Mayor Menino is set to announce the formation of a tax force designed to wring more PILOT monies from larger non-profit institutions.

But perceived inequities created by their tax-exempt status have long rankled some critics.

Combined, tax-exempt institutions give the city $32.4 million annually in payments in lieu of taxes, a drop in the bucket when compared with what the city spends on police, fire, and other services. If their properties were taxable, the institutions would be writing checks for 10 times that amount – between $350 and $400 million each year, city officials estimated yesterday.

“We want to ensure that each and every institution is paying their fair share,” Assessor Ronald W. Rakow said.

Considering Worcester pols are already using Boston as a model for their plans, we wonder if they’ll start asking for even more money before any was promised.
